Cumulative Problem 18 III One of the inevitable consequences of aging is a decrease in the flexibility of the lens. This leads to the farsighted condition called presbyopia (elder eye). Almost every aging human will experience it to some extent. However, for the myopic person, at some point, it is possible that far vision will be limited by a subpar far point and near vision will be hampered by an expanding near point. One solution is to wear bifocal lenses that are diverging in the upper half to correct the nearsightedness and converging in the lower half to correct the farsightedness. Suppose one such individual asks for your help. The patient complains that he can't see far enough to safely drive (his far point is 112 cm) and he can't read the font of his smart phone without holding it beyond arm's length (his near point is 85 cm)! Prescribe the bifocals that will correct the visual issues for your patient. 1) Calculate the power of the upper half of the bifocals. {Express your answer to three significant figures.) diopters Submit 2) Calculate the power of the lower half of the bifocals. {Express your answer to three significant figures.)
